ISDN Voice Box Answering Machine

ivam (ISDN Voice Box Answering Machine) is a
telephony application server system for ISDN and
Linux. It consists of two parts: a C-coded daemon
responsible for call setup, and high-level Python
scripted applications.

Release Notes: This is a complete rewrite. A daemon architecture
is used instead of a getty architecture. Call
disptaching was made more flexible. Multiple
channels per daemon and multiple telephony
applications per daemon are now supported. The
default voice box application is now more
powerful.
